The somatic sensory cortex (SI and SII) was mapped in llamas using microelectrode mapping methods developed earlier in a study of SI of the slow loris. Projections to SI from the llama's prehensile browsing lips were differentially enlarged when compared to those reported for sheep. In llama, SII was reversed in its mediolatreal pattern from that reported for SII in most other mammals. Fissural landmarks reliably demarcated different projections within SI, between SI and SII and between SI or SII and other surrounding nonsensory areas. The use of microelectrode mapping methods in different mammals to determine gyral and fissural homologies is discussed.
利用先前在懒猴体感皮层（SI）研究中开发的微电极映射方法，绘制了美洲驼的体感皮层（SI和SII）。与绵羊的情况相比，美洲驼用于抓握式啃食嘴唇的SI投射有差异地扩大。在美洲驼中，SII的内外侧模式与大多数其他哺乳动物中报道的SII模式相反。脑沟标志可靠地划分了SI内、SI与SII之间以及SI或SII与其他周围非感觉区域之间的不同投射。本文讨论了在不同哺乳动物中使用微电极映射方法来确定脑回和脑沟同源性的情况。
